Very strange, the demo crashes indeed (try to write at address $1) and 
goes back to gem, with the music still playing.

I didn't find the cause for now, as it's STF demo (no blitter or dma 
sound), could be a cpu emulation problem, but very hard to track among 
the whole demo.

I only got one of those after running it for several minutes. I think 
it's due to a bad routine where the demo doesn't write new dma sound 
addresses bytes in the correct order.
Maybe the other ones you saw were resolved by the recent changes in dev 
version.
